I think she starred in the film PINKY, about a black woman passing for white. Quite beautiful there, also.
IIRC “Pinky” was about the daughter of a black/white couple. The director was a controversial guy, can’t remember the name off hand, and the movie was reported to have caused quite a stir.
She might have been nominated for an academy award for this role.
Our library doesn’t have it, and that’s where I get most of her movies.
